Friendship clique and peer influences on body image concerns, dietary restraint, extreme weight-loss behaviors, and binge eating in adolescent girls.

This study explored friendship variables in relation to body image, dietary restraint, extreme weight-loss behaviors (EWEBs), and binge eating in adolescent girls. From 523 girls, 79 friendship cliques were identified using social network analysis. Participants completed questionnaires that assessed body image concerns, eating, friendship relations, and psychological family, and media variables. Similarity was greater for within than for between friendship cliques for body image concerns, dietary restraint, and EWLBs, but not for binge eating. Cliques high in body image concerns and dieting manifested these concerns in ways consistent with a high weight/shape-preoccupied subculture. Friendship attitudes contributed significantly to the prediction of individual body image concern and eating behaviors. Use of EWLBs by friends predicted an individual's own level of use.     

Do friends share similar body image and eating problems? The role of social networks and peer influences in early adolescence

This study examined the role of friendship networks and peer influences in body image concern, dietary restraint, extreme weight loss behaviours (EWLBs) and binge eating in a large community sample of young adolescent females. Based on girls' self-reported friendship groups, social network analysis was used to identify 173 friendship cliques. Results indicated that clique members shared similar scores on measures of dieting, EWLB and binge eating, but not body image concern. Average clique scores for dieting, EWLB and binge eating, were also correlated significantly with clique averages on measures of perceived peer influence, body mass index and psychological variables. Multiple regression analyses indicated that perceived peer influences in weight-related attitudes and behaviours were predictive of individual girls' level of body image concern, dieting, EWLB use and binge eating. Notably, an individual girl's dieting and EWLB use could be predicted from her friends' respective dieting and EWLB scores. Findings highlight the significance of the peer environment in body image and eating problems during early adolescence.     

The effect of school environment on body concerns in adolescent women

The study investigated body figure preferences, eating disorder symptomology, and role concerns in 142 Australian caucasian adolescent girls in two different school environments, both of medium to high socioeconomic status. Girls at a private single-sex school nominated a thinner ideal figure and displayed more eating disorder patterns than their counterparts at a private coeducational school. Although the schools did not differ in role concerns, these had a differential impact on prediction of the ideal figure. In particular, the importance placed on professional success predicted the choice of ideal figure for the single-sex but not for the coeducational school. It was concluded that what motivates the wish for thinness differed between the schools.     

Self-Perception Profile of Adolescent Girls at a Single-Sex and a Mixed-Sex School

The aim of this study was to investigate the association between attendance at either a single- or a mixed-sex school and scores on the Self-Perception Profile for Children (Harter, 1985). Subjects included 143 Northern Irish adolescent girls from a single-sex secondary school in Belfast and 24 adolescent girls from a mixed-sex secondary school matched for location and religious affiliation. Results indicated that girls from the single-sex school were less happy than girls at the mixed-sex school with respect to their physical appearance, but more satisfied with their behavioral conduct. In addition, physical appearance was the best predictor of global self-worth for girls at the mixed-sex school, whereas behavioral conduct was the best predictor of global self-worth for girls at the single-sex school.     

Adolescents’ preferences for sexual dimorphism are influenced by relative exposure to male and female faces

Exposure to a particular population of faces can increase ratings of the normality and attractiveness of similar-looking faces. Such exposure can also refine the perceived boundaries of that face population, such that other faces are more readily perceived as dissimilar. We predicted that relatively less exposure to opposite-sex faces, as experienced by children at single-sex compared with mixed-sex schools, would decrease ratings of the attractiveness of sexual dimorphism in opposite-sex faces (that is, boys at single-sex schools would show a decreased preference for feminised faces, and girls at single-sex schools would show a decreased preference for masculinised faces). Consistent with this prediction, girls at single-sex compared with mixed-sex schools demonstrated significantly stronger preferences for facial femininity in both male and female faces. Boys at single-sex compared with mixed-sex schools demonstrated marginally stronger preferences for facial masculinity in male faces, but did not differ in their ratings of female faces. These effects were attenuated among some single-sex school pupils by the presence of adolescent opposite-sex siblings. These data add to the evidence that long-term exposure to a particular face population can influence judgements of other faces, and contribute to our understanding of the factors leading to individual differences in face preferences.

The impact of adolescent girls' life concerns and leisure activities on body dissatisfaction, disordered eating, and self-esteem.

The aim of this study was to situate adolescent girls' body dissatisfaction, disordered eating, and self-esteem in the context of their life concerns and leisure activities. Questionnaires containing measures of life concerns, leisure activities, body dissatisfaction, disordered eating, and self-esteem were administered to 306 girls with a mean age of 16 years. It was found that although academic success and intelligence were rated as the most important life concerns, an emphasis on slimness was most strongly linked to body dissatisfaction, disordered eating, and global self-esteem. An emphasis on popularity with girls also was related to body dissatisfaction, and hours spent watching television were related to lower self-esteem. In contrast, emphasis on sport seemed to serve a protective function. It was concluded that adolescent girls who have a high concern for slimness should be assisted in decreasing this emphasis in order to improve their general well-being.     

Body image and disordered eating prevention in girls’ sport: A partner-driven and stakeholder-informed scoping review of interventions

Despite the evidenced benefits of participating in organized sport, adolescent girls consistently report lower rates of sport participation, worse sport experiences, and higher dropout rates, compared to boys. Body image concerns have been linked to this gender disparity and established as a critical predictor of disordered eating, thus necessitating effective prevention efforts to mitigate the negative impacts of body image concerns and disordered eating for adolescent girls. In partnership with the National Eating Disorder Information Centre (NEDIC; Canada), the present scoping review was conducted to examine the nature and characteristics of sport-specific body image and disordered eating interventions for adolescent girls. Fourteen studies were identified through various search strategies. Over half of the studies demonstrated modest yet worthwhile effects on various body image and disordered eating outcomes. Intervention characteristics (i.e., frequency, modes of delivery, topics, material, outcomes measured) varied across initiatives. Fifty-nine national, provincial, and local sport system representatives were consulted as stakeholders and provided practical input to the results of the scoping review. Sport stakeholders favoured the delivery of a multidimensional, multicomponent program, with a combination of evidence-based techniques. This synthesis of knowledge will shape the development and dissemination of future programs, and contribute to the development of equitable sport participation opportunities for Canadian girls.     

Eating behaviour, body image, and self-esteem of adolescent girls in Malaysia

This cross-sectional study was undertaken with 489 secondary school girls, ages 15-17 years, to examine disordered eating behaviours of adolescent girls in Malaysia and to estimate associations with body weight, body-size discrepancy, and self-esteem. Dietary restraint, binge eating, body image, and self-esteem were assessed using the Restrained Eating scale of the Dutch Eating Behaviour Questionnaire, the Binge Scale Questionnaire, the Contour Drawing Rating Scale, and the Rosenberg Self-Esteem Scale, respectively. Pearson correlations estimated associations between variables. There were 3.1% underweight, 9.8% at risk of being overweight, and 8.6% overweight girls. A total of 87.3% were dissatisfied with their own body size. Dietary restraint and binge eating were reported by 36.0% and 35.4%, respectively. Body Mass Index (r = .34, p < .01) and body-size dissatisfaction (r = .24, p < .01) were significantly associated with dietary restraint and binge eating, but self-esteem (r = -.20, p < .001) was significantly associated only with binge eating.     

Body image dissatisfaction among adolescent schoolgirls in Jordan

The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10–16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants’ preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed.     

Risk factors for disordered eating during early and middle adolescence: prospective evidence from mainland Chinese boys and girls

Despite evidence that sociocultural and psychological factors contribute to disordered eating, researchers have yet to examine the extent to which putative risk factors influence vulnerability for girls versus boys within and across phases of adolescence, particularly in non-Western cultures. In this study, early and middle adolescent samples from China (N = 2,909) completed measures of eating disorder pathology and putative risk factors at baseline and were reassessed 12 months later. Among both younger and older girls, elevations in appearance-focused interactions with friends, negative affect, and body dissatisfaction predicted increases in symptomatology at follow-up. In contrast, there was more discontinuity in risk factors relevant to samples of boys. Although media and friendship influences contributed to later disturbances among early adolescent boys, psychological factors, including body dissatisfaction and negative affect, had stronger effects in the multivariate model for older boys. Implications of finding are discussed in relation to adolescent development and a Chinese cultural context.     

A prospective study on the impact of peer and parental pressure on body dissatisfaction in adolescent girls and boys

The current study explores the role of appearance-related social pressure regarding changes in body image in adolescent girls (n=236) and boys (n=193) over a 1-year-period. High school students aged 11-16 completed measures of body dissatisfaction (i.e., weight and muscle concerns) and appearance-related social pressure from peers and parents. Three aspects proved to be particularly crucial: Parental encouragement to control weight and shape was a strong predictor of weight concerns in boys and girls alike; influences of friends affected gender-specific body image concerns by leading to weight concerns in girls and muscle concerns in boys; finally appearance-based exclusion was a predictor of weight concerns in boys. The findings provide longitudinal evidence for the crucial impact of appearance-related social pressure and suggest that a detailed assessment of different types of social impacts can identify concrete targets for effective prevention and therapy for weight-related problems among adolescents.     

Influence of Mass Media on Body Image and Eating Disordered Attitudes and Behaviors in Females: A Review of Effects and Processes

This article reviews research on the effects of television and magazines on body image and on disordered eating attitudes and behaviors in females. Evidence from different types of studies in the fields of eating disorders, media psychology, health psychology, and mass communication indicates that mass media are an extremely important source of information and reinforcement in relation to the nature of the thin beauty ideal, its importance, and how to attain it. Although considerable research remains to be done, evidence is accumulating that repeated exposure to media and to both direct and indirect (via media's effects on peers, parents, coaches, physicians, etc.) pressures from media to be thin constitute risk factors for body dissatisfaction, concerns over weight and disordered eating behaviors in adolescent girls and young women. To guide further research, as well as the prevention and treatment of disordered eating, we present a figural summary of media effects that integrates moderating and mediating factors such as internalization of the thin beauty ideal, social comparison, and activation of the thinness schema. We argue that risk factor research, prevention, and treatment will benefit from systematic research designed to clarify how the impact of various mass media is shaped by source and receiver/perceiver factors.     

Career Aspirations of Adolescent Girls: Effects of Achievement Level,Grade, and Single-Sex School Environment

The career aspirations of high-achieving adolescent girls were explored by comparing them to the aspirations of adolescent boys as well as by looking at the influence of grade in school, achievement level, and an all-girls school environment. The participants' ideal and real career aspirations, scored in terms of prestige, were investigated via 2 sets of analyses , with coed (n = 704) and single-sex female (n = 494) adolescent samples. Results showed that high-achieving girls exceeded the aspirations of average-achieving girls and boys, and were the same as those of high-achieving boys. Gender and grade differences in ideal and real career choices over all achievement levels are also reported and discussed. Girls at single-sex schools had higher real career aspirations than did girls and boys at coed schools.     

Sociocultural correlates of compulsive exercise: is the environment important in fostering a compulsivity towards exercise among adolescents?

Sociocultural factors hypothesised to be influential in eating disorders were assessed for their relationship with compulsive exercise. A sample of 828 adolescent boys and girls completed measures assessing sociocultural messages to change body shape as well as pressure to be thin, and also measures of compulsive exercise and disordered eating. Results showed that the sociocultural influences differed slightly between boys and girls. Hierarchical regressions showed that, after controlling for disordered eating and BMI, messages to become more muscular and media pressure to be thin significantly predicted compulsive exercise in boys, while the same regression in girls reported only media pressure to be thin as a significant predictor of compulsive exercise. These findings demonstrate the influence of the media in boys’ and girls’ compulsive exercising, as well as highlight the influence of body shape messages to become more muscular on boys’ compulsive exercise.     

Influence des médias,insatisfaction envers le poids et l’apparence et troubles alimentaires selon le genre

The aim of the study was to explore gender differences in weight dissatisfaction, body dissatisfaction, media influence, use of dieting and excessive exercise, and disordered eating among a sample of 405 adolescents and young adults (277 girls and 128 boys) aged between 15 and 26. Girls were more likely to want to lose weight, whereas boys were more likely to want to gain weight and use excessive exercise. Gender differences have been found in body dissatisfaction and media influence, and among participants with disordered eating too. The findings brought out the gender-specific patterns of media influence, body image disturbances and disordered eating.     

SINGLE-SEX VERSUS MIXED-SEX CLASSES AND GENDER SCHEMATA IN CHILDREN AND ADOLESCENTS

Positive effects for women and girls of all-female schools have been proposed, although there is relatively little clear empirical support for these beneficial results. Much of the cited research is based on elite all-female institutions or on parochial schools. This study takes advantage of the change of a private, nonparochial school from all girls to both sexes. Longitudinal data from grades 2 through 12 were collected over the course of the academic year to study the results of this transition. Stereotyping declined with age and over time in both types of class-rooms. Girls in single-sex classrooms showed some tendency to be more stereotyped in their perceptions of mixed-sex classrooms than did the girls who were actually in that setting. Thus, none of the measures showed any significant increase over time in stereotyping among girls in mixed-sex classes. Implications of these findings are discussed.     

Friendship cliques: a comparison of the motivational traits of lower/upper track algebra students

This project examined the relationships among the motivation and cognitive profiles of adolescent friendship cliques and peripheral (outside the clique group) students in lower and upper track algebra classes. Two hundred and thirty students from two high schools completed a motivation and cognitive engagement instrument as well as a peer group nomination survey form. Twelve teachers were also asked to complete peer group nomination survey forms. This project used socio-metric and correlational techniques based on previous research traditions in exploring friendship and peer group research to examine these relationships. The results were consistent with theoretically driven predictions and extend previous findings of the impact of friendship cliques in lower grade levels to those of adolescents in the high school setting. Future research in adolescent friendship/clique group research is also discussed.     

Healthy Schools-Healthy Kids: a controlled evaluation of a comprehensive universal eating disorder prevention program

This study was a controlled evaluation of a comprehensive school-based universal prevention program involving male and female students, parents, teachers, school administrators and local public health professionals. A total of 982 male and female Grades 6 and 7 middle school students (and 91 teachers/school administrators) completed self-report surveys at baseline on measures of body satisfaction, internalization of media ideals, size acceptance, disordered eating, weight-based teasing, weight loss and muscle-gaining behaviours, and perceptions of school climate (teachers only). Eighty-four percent of the students repeated the surveys immediately following the 8-month school-wide intervention and 71% again 6 months later. Repeated measures ANCOVAs revealed that participation in the Healthy Schools-Healthy Kids (HS-HK) program had a positive influence by reducing the internalization of media ideals among male and female students and by reducing disordered eating among female students. The program was also associated with reductions in weight-loss behaviours among the students, although this effect was lost by the 6-month follow-up. When the intervention students were sub-divided into low versus high-risk groups, the high-risk group appeared to benefit most from the intervention with significant reductions in internalization of media ideals, greater body satisfaction, and reduced disordered eating over time. There were no intervention effects for teachers. Challenges of engaging teachers in prevention are discussed.
